In today’s connected world, businesses need their point-of-sale (POS) systems to communicate seamlessly with companion mobile applications. But what happens when your POS is built on older technologies, such as SQL Server 2005 and Delphi, with no modern APIs? Many businesses face this exact challenge: integrating a legacy POS with iOS and Android apps to exchange critical data like orders, menus, and statuses.
The solution: a lightweight Windows-based Sync Agent that acts as a bridge between your POS and mobile applications.
